Detailed Description
For a clearer understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals refer to identical or structurally similar but functionally identical components throughout the separate views.
In this document, "schematic" means "serving as an example, instance, or illustration," and any illustrations, embodiments described herein as "schematic" should not be construed as a more preferred or advantageous solution.
For the sake of simplicity of the drawing, the parts relevant to the present invention are shown only schematically in the figures, which do not represent the actual structure thereof as a product. In addition, for simplicity and ease of understanding, components having the same structure or function in some of the figures are shown schematically only one of them, or only one of them is labeled.
Herein, "a" means not only "only this one" but also "more than one" case. Herein, "first", "second", etc. do not indicate the degree of importance or order thereof, etc., but merely indicate distinction from each other to facilitate description of documents.
Referring to FIG. 1, a flow chart of a method of identifying components in a system diagram is shown, in accordance with one embodiment of the present invention. The method may preferably be performed by the computing device 900 or computer processor shown in fig. 3. It should be appreciated that the method may be performed by other means, such as a device or other computing device that identifies components in a system diagram as shown in fig. 4.
Step S1: and acquiring a drawing pick-up area and a drawing type of the electrical drawing. A primary system diagram file can comprise a plurality of electrical drawings, and a user can select the electrical drawings to be identified through a mouse frame so as to determine a drawing pickup area. The drawing types can be divided in various manners, for example, whether the parameter marks of the same type of components in the electrical drawing have the same or basically the same abscissa/ordinate, or whether the parameter marks of the same type in the electrical drawing have the same or basically the same labeling manner can be judged. In an actual implementation, the drawing type may be determined by software, or manually selected by a user.
Step S2: and acquiring a module pickup area and a module identifier of at least one module in the drawing pickup area. The modules may be "switch cabinets" or otherwise. One or more modules may be included in an electrical drawing. The module locations in the electrical drawing templates may vary from design company to design company. The position of the component in the module in the drawing can be determined by acquiring the module pick-up area. The method is realized by the following steps: a user selects a module identifier (such as a switch cabinet label) of a specific module in the electrical drawing, and a wire closest to the module identifier in the electrical drawing can be obtained according to the frame selection position; according to the frame wires, the area range of the components in the module can be obtained. Generally, the longitudinal wire on the left side of the module identifier, which is closest to the module identifier, and the longitudinal wire on the right side of the module identifier, which is closest to the module identifier, together define the abscissa range of the component distribution within the module. Similarly, for other parts of the electrical drawing, the vertical coordinate range of the component distribution in the module can be defined by the transverse frame line above the module mark and closest to the module mark and the transverse frame line below the module mark and closest to the module mark.
Step S3: and determining a component identification rule of the module based on the drawing type and the module pickup area.
Step S4: and identifying the components in the module according to the component identification rule, and storing the module identification, the component category and the component initial identification.
When the drawing type of the electrical drawing is the first type, the labeling modes of the parameter marks in the electrical drawing are unified, and the parameter marks of the same type of components have the same/basically same labeling modes, as shown in the table 1. When the drawing type of the electrical drawing is the second type, the parameter marks in the electrical drawing are arranged in a table-like manner, and the parameter marks of the same component have the same or basically the same abscissa or ordinate, as shown in table 2. Tables 1 and 2 show only part of information of the electrical drawings, for schematically illustrating the types of the electrical drawings.
TABLE 1 local information of first type of electrical drawing
Preferably, the step S3 may include step S301: if the drawing type is the first type, searching a teaching identifier corresponding to at least one component category in the module, and determining a component identification rule of the module based on the module pickup area and the teaching identifier. Specifically, when the drawing type of the electrical drawing is the first type, the parameter marks of the same type of components have the same/substantially same labeling mode. For example, in table 1, the same/substantially the same labeling manner is used for all parameter labels in the switch cabinets "1AA5", 1AA6 "and" 1AA7", and, for example," MCCB "is used as the beginning of the parameter label, and there are parameters that are different, but have correspondence with each other. For example, when the components in the switch cabinet "1AA5" are to be identified, the abscissa range of the parameter mark in the switch cabinet "1AA5" is obtained in step S2, the teaching mark corresponding to a component category is found and obtained as "MCCB250N", and the corresponding component category in the loop can be identified after comparison of similar keywords in the abscissa range. Wherein the above teaching identification "MCCB250N" is for illustration only, other forms, such as "MCCB" etc., may also be employed.
As an example, step S301 may further include step S3011: and if the teaching identification is not found, acquiring the component category and the identification input by the user, and determining the teaching identification based on the identification. For example, if the component is not set or stored with a "teaching identifier", the teaching identifier may be obtained by teaching. Specifically, the user selects one parameter mark "MCCB250N tmd2503p+sde+of M3" in a frame, so as to obtain an identifier "MCCB250N tmd2503p+sde+of M3" of the component, and determines that the corresponding teaching identifier is "MCCB250N" through the identifier. The above teaching identifier MCCB250N is for illustration only, and other forms may be used without limitation.
When teaching is required to be carried out on the components of multiple types in the module, a user can select one component type and input a specific identifier, then select the next component type and input the specific identifier until the teaching of all the required component types is completed. In addition, the invention also provides a guide teaching method, namely, the identification is acquired sequentially based on the input sequence of the component types. Specifically, before teaching, a user firstly selects all required component categories, then inputs identifiers one by one (specifically, the identifiers can be obtained through parameter marks in a frame selection drawing), and the method corresponds the component categories and the identifiers according to the input sequence of the component categories. The component categories can be cabinet numbers, circuit breakers, contactors, thermal relays, transformers, meters, position numbers and the like.
TABLE 2 local information of electrical drawings of the second type
Preferably, the step S3 may include step S302: and if the drawing type is the second type, searching a teaching pickup area corresponding to at least one component type in the module, and determining a component identification rule of the module based on the module pickup area and the teaching pickup area. Specifically, when the drawing type of the electrical drawing is the first type, the parameter marks of the same type of component have the same or substantially the same abscissa or ordinate. As shown in Table 2, in the switch cabinet labeled "216MC03MC07", the parameter labels "MCCBS 160R 20 MA 200/20", "MCCBS 160R 52 MA 520/52", "MCCBS 160R 20 MA 200/20" … … "MCCBS160TMD32/4P 500/32" of one type of component have the same ordinate. Step S2 yields the abscissa range of the parameter markers within the switch cabinet "216MC03MC 07". When the type of components in the switch cabinet are to be identified, a teaching pickup area corresponding to the type of components in the switch cabinet body is searched, wherein the teaching pickup area can be a certain ordinate value, a range of the ordinate value, and a relative distance or a range of the relative distance of the type of parameter mark relative to the switch cabinet mark '216 MC03MC 07' on the ordinate. By means of the module pick-up area and the teaching pick-up area, the specific positions of the corresponding components can be determined for identification.
As an example, step S302 may further include step S3021: and if the teaching pickup area is not found, acquiring the component category and the frame selection area input by the user, and determining the teaching pickup area based on the frame selection area. For example, a "teaching pickup area" is not set or stored for such components, and is obtained by teaching. Specifically, the user selects one of the parameter marks MCCBS 160R 20 MA 200/20 to obtain the position information of the component or the longitudinal frame line information near the component, and the teaching pickup area corresponding to the component category can be determined through the frame selection area.
When teaching is required to be carried out on the components of multiple types in the module, a user can select one component type and then input the frame selection area, then select the next component type and then input the frame selection area until the teaching of all the required component types is completed. This approach is cumbersome. In addition, the invention also provides a guide teaching method, namely, the frame selection areas are sequentially acquired based on the input sequence of the component types. Specifically, before teaching, a user firstly selects all required component categories, then inputs the frame selection areas one by one, and corresponds the component categories and the frame selection areas according to the input sequence of the component categories.
The method of the present invention may be used in either step S301 or step S302, or both. The method of step S301 can accurately identify the electrical drawing with the uniform labeling mode of the parameter marks, and the method of step S302 can accurately identify the electrical drawing with the same or basically the same abscissa or ordinate of the parameter marks of the same kind of components.
Referring to FIG. 2, a flow chart of a method of identifying components in a system diagram is shown, according to another embodiment of the present invention. After step S4, steps S5 and S6 are further included. As an example, step S6 may be omitted.
S5: and analyzing the initial identifier of the component according to a preset identifier analysis rule or a user-set identifier analysis rule to acquire the parameter information of the component.
Because the labeling styles of the designers are greatly different, various different expression modes exist for the initial identifiers of the components obtained in the step S4, so that the initial identifiers of the components cannot be directly used. Therefore, the initial identification of the component needs to be analyzed to obtain the parameter information of the component. Specifically, the identification analysis rule can be obtained by analyzing the existing data in advance, the identification analysis rule is pre-stored, and then the initial information of the component is analyzed according to the preset identification analysis rule in step S5; and the analysis can be performed according to the identification analysis rules set by the user in the using process.
S6: order numbers of the components are determined based on the parameter information. Although, the parameter information of each component may be obtained in step S5. However, for a plant to place an order for a particular component in a supplier, the order needs to be known, and each supplier has its own order naming convention. The engineer can be assisted to quickly acquire order numbers of different suppliers to provide work efficiency through step S6. Specifically, a mapping between the component parameter information and the order numbers of the suppliers may be preset, and the order numbers of the corresponding components may be obtained through a mapping relationship.
Preferably, the step S4 may be followed by the step S5, which may further include a step of setting an identification resolution rule by the user: s500: at least one parameter field selected by a user from the initial identifier of the component is obtained, the electrical parameter type selected by the user for the parameter field is determined, the analysis rule corresponding to the electrical parameter type is determined and stored based on the parameter field, and the identifier analysis rule comprises at least one analysis rule. Through teaching and word dividing, corresponding keywords are divided and then manually judged to point to corresponding electric parameters, specifically, by taking an initial identification of an element of 'MCCB 100N 100 TMD 3P 3D/plug-in' as an example, a user divides and selects 'MCCB' and points to 'serial names', a user divides and selects '3P' and points to 'pole number', a user divides and selects 'TMD' and points to 'tripper attribute', a user divides and selects '100' and points to 'frame current parameter value', and the like. While the data is being drawn, the data is stored in a database and categorized by brand, series. And when the new initial identification of the component is analyzed next time, directly selecting the model according to the rules recorded in the database.
